Sperm Whale
Flukes are lifted very high out of the water before a whale begins a deep dive.
Sperm whales are believed to be able to dive up to 3 km (1.9 miles) in depth and 90 minutes in duration to the ocean floor. More typical dives are around 400 m (437 yards) in depth and 30–45 minutes' duration and generally move in a northerly direction. They carry three tonnes of blood which holds enough oxygen to help it achieve its diving depth.
